Patent JP-S62969-A (JP)
Title: Image forming device
Inventor: YASUGURO YOSHINORI
IPC: G03G15/01
Filed: 1985-06-27
Abstract: PURPOSE:To obtain an image having uniform quality by setting the peripheral speed of an image carrying body during the operation of a developing device on a down stream side at the speed higher than the peripheral speed of a developing device on an upper stream side so that the time since the electrostatic charge of the image carrying body until the arrival of said body at each developing deice is made approximately equal. CONSTITUTION:The input signal corresponding to the developing device to be used is supplied to the input of a main controller 20. The controller 20 applies the signal to instruct the predetermined rotating speed of a photosensitive drum 1 to a motor revolution control circuit 21. The circuit 21 controls a photosensitive drum driving motor 22 to the instructed speed. For example, the time twice longer than the time when the developing device 6 on the uppermost stream is used is required in the stage of using the developing device 8 on the lowermost stream and therefore the rotating speed of the drum 1 is so controlled as to be made twice faster. Then the time since the drum 1 is electrostatically charged by a corona discharger 2 until the drum arrives at the device 8 is made approximately equal to the time when the drum 1 arrives at the device 6 when the device 6 is used. The dark potential on the drum 1 is thus maintained at approximately the same value.

IPC: G01R31/3183
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To efficiently compress a test pattern set of a logic circuit. SOLUTION: A test pattern order change means 103 changes the arrangement according to the order starting from least number of uncertain value for a plurality of test patterns included in an initial test pattern set generated by an initial test pattern generation means 102. When the arrangement of test patterns is not changed according to the number of uncertain values, the test pattern order change means 103 changes the arrangement of test patterns according to the generated pseudo-random number. After that, test patterns are mutually joined by a test pattern join means 106 after processes by an uncertain value reactivation means 104 and an uncertain value determining means 105. The test pattern which cannot detect a failure is destroyed in the uncertain value determining means 105.  As for the test pattern set in which test patterns are joined, the arrangement of test patterns is changed further in the test pattern order change means 103, and the same processes are repeated.

Abstract: PURPOSE:To prevent a running speed from making a sudden change by making a speed change valve as a rotary valve to set an angle of distributing more operating oil to an acceleration side port of a hydraulic cylinder from its deceleration side in a speed change holding position, and making the speed change valve balance an oil pressure in the acceleration side with that in the deceleration side in a speed change position. CONSTITUTION:When a speed change lever 71 is shifted to a speed change position from a neutral position, a continuously variable transmission is speed change-operated to a preset speed by opening a speed change valve 75 to an acceleration side to extend a hydraulic cylinder 73, and the speed change valve 75, following up the above, is successively return-operated by a feedback mechanism and reset to a speed change holding position where the hydraulic cylinder 73 is not telescopically operated. In the speed change holding position, the speed change valve 75, formed of a rotary valve, is placed at an angle of distributing more operating oil to an acceleration side of the hydraulic cylinder 73 from its deceleration side. Under this condition, when the speed change lever 71 is shifted to the other speed change position, the speed change valve 75 is turned from a balanced condition of distributing the operating oil to acceleration and deceleration sides, so that a smooth speed change can be made.
